Is there a way to use a PDA as a remote control for a home entertainment system?
Having your PDA serve double duty as a home-entertainment remote control is a very appealing idea. Because PDA software can be upgraded so easily, you can add new remote features and device control codes as you purchase new equipment. Also, PDA remote-control software can support configurations for several systems. Unfortunately, whereas the consumer infrared (CIR) transmitters used in most consumer entertainment devices have a range of up to 30 feet, PDA infrared (IrDA) is typically rated to work at a maximum of 3 to 8 feet. But all is not lost.
